Therefore, these products with defined 5' and 3' ends accumulate exponentially with each round of DNA amplification -- that is, for every n cycles of PCR there will be 2 -fold amplification of the specific DNA fragment.

The term trisomy refers to the presence of three representative chromosomes in a cell instead of the usual pair. In Down syndrome the twenty-first chromosome pair fails to separate when the germ cell (usually the ovum) is being formed.he majority of cases of Down syndrome occur due to an extra chromosome 21 within the egg cell supplied by the mother (nondisjunction). As a woman's age (maternal age) increases, the risk of having a Down syndrome baby increases significantly. For example, at younger ages, the risk is about one in 4,000.
